GENERAL DESCRIPTION OF THE INVENTION

Petition 870180069333, of 08/09/2018, p. 9/34

6/10 [016] The present invention essentially comprises a device developed including a bucket with compartments or modules for housing bulk products with a volume of 1 m ³ , under which the bucket is a hydraulically driven conveyor. The compartments or modules are operated independently by hydraulic cylinders, using levers incorporated into a hydraulic system, allowing the opening or closing of individual hatches in each compartment, as desired.

[017] The conveyor under the bucket receives material from the compartments, from the opening of the hatches, a procedure that is done individually by means of manual actuators for the hydraulic flow, in order to open or close the hatches.

[018] As can be seen in the drawings, the conveyor has a concave conformation, in order to allow the unloading of the material from the bucket out of the body, where it can be discharged into the dosing bucket accessory with a movable spout, where it is planned to control volume to be distributed.

[019] Therefore, the invention contemplates the disposition and conditioning of loads and discharges of bulk products, in automatic and differentiated fractioning conditions, making it possible to adapt them in compartments with exact volumes, weights and measures, with differentials for effective and efficient unloading. .

DETAILED DESCRIPTION OF THE INVENTION [021] THE FRACTIONAL BULK LOADING AND UNLOADING DEVICE, object of this invention patent application, consists of a fractional bulk loading and unloading device (1) that is applied over dump truck buckets (2) or others, or, in a constructive variation, on the chassis of cargo vehicles (3), composing solutions in the size of the body.

Petition 870180069333, of 08/09/2018, p. 11/34

8/10 [022] The fractional bulk loading and unloading device (1) comprises a bucket (4) with a plurality of geometric compartments (5) designed to receive products of at least one variety, each mentioned compartment (5) provided with independent activation of a hatch (6) to open or close said compartment; said compartments (5) aligned on a concave-shaped conveyor (7), hydraulically driven, like the hatches (6), so that this conveyor (7) carries the product out of the body where it can be discharged into the dosing bucket accessory discharge (8) with movable spout (9), where controls (10) determine the exact measurements of the products to be released.

[023] The bucket (4) is preferably positioned on a structure (11), whose distal points receive load cells (12) to determine the weight of the set and, consequently, the products transported.

[024] Hydraulic pistons (13) are provided on the sides of the silos (compartments), as many as the number of geometric compartments (5), with one end of each mentioned hydraulic piston (13) coupling to the hatch (6) and , the opposite end, attaches to the structure (11).

[025] The hydraulic system (14) connected to the hydraulic pistons (13) is controlled by conventional levers (15), connected to an oil pump (B), filters (F) and oil reservoir (R1), strategically arranged; having an oil supply line (L1) and an oil return line (L2).

[026] The conveyor (7) is driven by a hydraulic motor (19) controlled by a conventional lever (15) connected to an oil pump (B), to filters (F) for outlet and return, and these to the reservoir of oil (R1), strategically arranged; having an oil supply line (L1) and an oil return line (L2).

[027] At the conveyor outlet, the discharge metering bucket accessory (8) can be coupled, which reveals a movable spout (9) with a hinged lid with a lock (16) which, from the controls (10), makes it possible to fractionate more once in exact quantity of product to be released.

Petition 870180069333, of 08/09/2018, p. 12/34

9/10 [028] In reality, the discharge metering bucket accessory (8) has a capacity in exact measurements according to the volume capacity of the referred discharge metering bucket (8), preferably between 0.5 and 1m ³ , providing accuracy of measurements when unloading bulk products. Once closed and locked, the hinged lid with lock (16) of the movable spout (9), the discharge metering bucket (8) is completely filled; after filling, simply unlock the hinged lid with lock (16) manually to drain the product from inside the discharge dosing bucket (8).

[029] The mat (7) has a concave shape determined by lateral components (17), on both sides, with the objective of inducing, by contact, the mat (7) to acquire the referred concave configuration, so that the material is transported from the geometric compartments (5) out of the body where it can be unloaded in the discharge metering bucket accessory (8).

[030] In the variation shown in Figures 12 to 14, the invented bucket (4) is coupled to a chassis (3) of a cargo vehicle, said body (4) being composed of the same compartments (5), conveyor (7) ) and the movable spout accessory (9) with the same technical resources, including the same hydraulic operations.

HYDRAULIC OPERATION OF THE DEVICE [031] For opening one or more geometric compartments (5), the line (L1) represents the oil injection and the line (L2) the oil return to the oil reservoir (R1). In the condition of closing the geometric compartment (5), when pushing the conventional lever (15), the oil is sent to the bottom of the hydraulic piston (13), forcing the piston to move upwards and the consequent retraction of the rod that promotes opening the hatch (6) for closing the first geometric compartment (5); the same is repeated for the others (Figure 1).

[032] For closing one or more geometric compartments (5), the line (L1) represents the oil injection and the line (L2) returns the oil to the oil reservoir (R1). In the condition of closing the geometric compartment (5), when pulling the conventional lever (15), the oil is sent to the top of the hydraulic piston (13), forcing the movement of the piston downwards and the consequent expansion of the

Petition 870180069333, of 08/09/2018, p. 13/34

10/10 rod that promotes the closing of the hatch (6) of the first geometric compartment (5); the same is repeated for the others (Figure 2).

[033] In the operation of the belt (7), the line (L1) represents the oil injection and the line (L2) the oil return to the oil reservoir (R1). Through a lever with lock (15), the oil is directed to the hydraulic motor (19), and this, in turn, turns the traction roller (18) that gives movement to the rubber belt of the belt (7 ) shipping company. Once in operation it will transport the material coming from the geometric compartment (5) that is open towards the exit of the body, where you can have the discharge dosing bucket accessory (8) of the movable spout (9).

[034] The discharge metering bucket (8) has adjustment controls (10), in addition to being fixed to the body using screws; this facilitates removal for maintenance, replacement and other procedures.
